WEB-CUTTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 608,624, dated August 9, 1898.-

Application filed April 21, 1896.

York, (Brooklyn,) county of Kings, and Stateof New York, have invented certain new and useful Improvements in VVeb-Outting Mechanism, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

cutting webs of material into sheets and de livering the same, being especially designed for use as adclivery mechanism of that class of printing-m achines which print long lengths or webs of paper required to be severed into short lengths or sheets,which sheets are to be delivered either singly or with two or more associated and in either case folded or flat.

In the accompanying drawings, Figure 1 represents so much of a side elevation of a printingmachine as is necessary to illustrate the practical use of these improvements. Fig. 2 is an enlarged sectional elevation of the group of associated carriers A B C in which these improvements are embodied. Fig. 3 is an enlarged plan View of said carriers, the central portions of which are removed to accommodate the proportions of the View. Figs. 4, 5, 6, and 7 are still more enlarged sectional views of portions of the carriers A B, showing the mechanisms thereof in different positions of their operative movements.

These improvements are shown herein as embodied in a web-perfecting printing-machine, which will be generally described in order that the improvements may readily be understood.

In Fig. 1 is shown the last impression-cyh 4o inder I and last type-cylinder T of a web-perfecting printingmachine, and the printed web W therefrom is shown as passing over guiding-rollers 50 60 70 to and between the rotating carriers A and B of a delivery mechan ism, said delivering mechanism additionally having in this instance a delivering-cylinder 0. As the invention is comprised within this delivery apparatus, no further description of the printing-machine is necessary, except tosay that it is a common construction in the art and may have substituted for it any other Serial N0. 588,444. (No model.)

ments' combined with them in the same manner or substantially as is hereinafter described ,in detail, said delivery mechanism having a delivery-cylinder C or any other means for disposing of the sheets produced by the mechanis'm embodying the improvements. I0 These improvements relate to means for 1 'In order to provide for the continuous onward movement of a web of paper that is severed into sheets and the like continuous move ment of the sheets severed therefrom, sheetcarrying pins have been provided to impale the forward end of the sheets, and thus cause the onward movement of the web when a sheet has been severed therefrom, which forwarding-pins require no space between sheet and I sheet for their engagement with the leading end of such sheet length and enable said continuous onward movement to be performed; but at the present day, when fine work is required, especially in bookwork, the perforations made by these pins in the leading end of 7 5 the sheet are great objections, because they mar the work when the paper composing the sheet is entirely used or entail a loss by trimming the edges of the book in order to remove the parts containing these pin-holes, thus causing a loss of material and additional expense to the work. To avoid these holes, a

novel constructionand arrangement of grippers 6 has been made, which will be best understood from Figs. 2 and 4 to 7, inclusive.

The rotating carrier A is preferably of such a size that it aids in the production of three sheets at each revolution, and it is, according to its size, provided with one, two, or more sets of grippers 6, each of which is mounted on a rock-shaft 10, provided with a cross-head 11, one end of which is connected to a springrod 24, acting to hold the grippers closed, and

the other end of which carries a stud or bowl contacting with cams X and Y, by which said 5 shaft is vibrated, as is common, to open and close said grippers. These grippersihhowever,

are so shaped that they do" not protrude be yond the periphery of the carrierA, but, on the contrary, make a sweep which is nearly coin- IOO cident with the curved peripheryof the carricr A, the center of their carrying-shaft l0 the end of the paper.

being directly under or in a radial line with the points of the grippers when closed, (see Fig. 2,) so that in opening the are described by the points of the grippers will be within the periphery of the cylinder, thus allowing the grippers 6 to be opened underneath the incoming web without puncturing or contacting with it. \Vhen closed, these grippers 6 press upon an an gnlar-faced bearer 9, inclined inwardly from the periphery of the carrier A, but so shaped between the gripper-points as to provide a space or cutting-slot 2, that will be bridged by the passing web. For cooperation with these grippers 6 the companion carrier 15, having a circumferential extent equal to that of two sheets, carries two sets of presser-fingers 7, each set of which is hung upon a rock-shaft 12, that is provided with a rock-arm 20, one end of which is attached to a spring-rod 25,whereby the fingers are springseated,so that they are normally held inwardly or within the periphery of the carrier B, as in Fig. 4:, and which shaft 12 has the other end of its rock-arm 20 provided with a stud or bowl, whereby it is rocked to project the fingers into action by its contact with a stationary cam 21. As these presser-fingers 7 at times sweep within the peripheral line of the carrier A for cooperation with the grippers 6 and both are momentarily closed against the angular bearer 9, (see Fig. 2,) the grippers 6 have their outer ends recessed, as shown in Fig. 3, to provide for this conjoint action in holding The carrier A is of course provided with recesses, in which the grippers (3 and the fingers 7 may sweep. The carrier B is provided with a stationary projecting knife 13, furnished, as is usual, with a spring-seated or elastic presser-block 14:, (see Fig.- 4B,) which knife moves against said web and severs it by perforating that part of the web which bridges the space or cuttingslot 2 in the carrier A, and as the fingers sweep close to the blade 13 the presser-block 14 has recesses 5 to permit of this movement.

As the mechanisms embodying these improved sheet-carrying devices are provided with means forfoldin g the sheets thus formed, the same will be described in order that the delivery of the sheets as an entirety may be best explained in the description of the operation.

The carrier A is provided at points midway between the grippers 6 with rotative folding or tucking blades 15, that are mounted upon rock-shafts 8, each provided with a rock-arm connected to a spring-rod 27, whereby said blades 15 are normally held within the carrier 13, said shaft also having a rock-arm 16, that contacts with a cam D, to cause said blade to vibrate or swing outward in performing the tucking or folding operation, as in Fig. 7. The carrier B is also provided with two sets of nipping-jaws. In each set there is a stationary jaw 3 and a movable jaw 17, the latter being carried by a rock-shaft that is provided with a cross-head 23, one end of which is attached to a spring-rod 28, whereby the said movable jaw is normally held closed and its other end provided with a stud or bowl, whereby through contact with a stationary cam E is held open at the proper periods of time. (See Fig. 7.) The carrier 0 is provided with two sets of ordinary grippers 19, projecting from shafts 30, that carry cross-heads 18, one end of which is attached to a spring-rod 29, whereby they are normally held closed, and the other end of which head carries a stud or bowl that contacts with a fixed cam F,whereby said grippers are properly opened to receive the folded sheet from the nipping-jaws 17 and deliver the same. In this instance the carrier O has tapes 22 running around it and in contact with the carrier 13, which tapes aid in the performance of the folding operation.

As the carriers rotate in unison and the grippers (3, carried by the carrier A, and the cutting-blade 13, carried by the carrier B, are approaching the point of nearest contact between these carriers (see Fig. 4) the web W will be laid upon the periphery of the carrier A, overlying the cutting-slot 2 in the carrier A, the grippers 6 then standing open, but on the rear side of the web W, then stretched over them.

WVhen the carriers AB have advanced these mechanisms to the position shown in Fig. 5, the spring-seated presser-block 14 will bear upon the paper web each side of the cuttingslot 2 in the carrier A and hold the web while the cutting-blade 13 is forced through the same to sever a sheets length therefrom as the carriers A B move onward. Simultaneously with this cutting action the fingers 7 are swung outwardly by the action of the cam 21 on the rock-arm 20, thus pressing the front edge of the web W, then overlapping the angular bearer 9, as in Fig. 6, this action being slightly in advance of the closing movement of the grippers 6, caused by their rockarm 11 descending onto the low part of the cam X, which gripper movement made, as before stated, in an are that swings their points behind the web, seizing said web by bearing it against the angular face of the bearer 9, the bifurcated ends of said grippers 6 moving past the projecting points of the fingers 7 and pressing the web end onto the bearer. This disposition of the grippers 6 is maintained long enough to carry the leading end of the web a half-sheets length dis tant from the point where the web was severed, as in Fig. 7, whereupon said grippers are opened by the action of cam Y to release the end of the web (see dotted lines, Fig. 7) simultaneously, or thereabout, with the rocking movement of the tucking-blade 15, caused by the high part of the cam D, which acts to tuck the middle transverse portion of the sheet into the recess in the carrier B, in which the jaws 17 vibrate, which jaws make this movement by the action of the cam E in such manner as to receive the doubled or folded part formed by the tucking-blade 15 and allow said blade to be removed therefrom and the sheet length to be clamped by said jaws 17, so that thereafter it will move with the carrier I as is shown bythe dotted lines in Fig. 7, and its tail end will be lapped upon the companion half of the sheet it partly forms. The continued rotative movement of these carriers causes the folded sheet to be laid upon the carrier B, (see Fig. 2,) and it is finally delivered therefrom in a manner too well understood to need any detailed description. \Vhen the cutting-blade and the fingers of the carrier B come into cooperative position with respect to the next set of grippers G, the cutting operation is again performed, the leading end of the web is seized by the grippers 6, and the described folding and deliverin g operations are repeated. By this improved construction and operation of the mechanisms the web is severed to divide it into sheet lengths without losing the continuity between sheet and sheet. The leading end of the web formed by the cutting operation and which otherwise would be free is not only clamped to the cylinder A by the fingers 7, but this clamping of it is maintained for a period that will enable the rotative movement of the carrier 13, supporting these fingers, to withdraw the cutting-knife out of the carrier A, thus enabling the grippers 6 to unobstructedly make their sweeping movement in closing down upon the end of the sheet while it is held by the fingers 7 onto the carrier A and seize the same by clamping it to the inclined face of the bearer 9. This accomplished, the fingers 7 are by the further rotative movement of the carrier B withdrawn from the end of the web, and it is then Wholly controlled by the grippers 6. These grippers are thus enabled to move in both directions without contact with the overlying paper or the cutting-blade 13, the web is positively and continuously held and moved onward, and the sheets are produced without any abrasion of their leading ends either upon the surface or through the body thereof.

This invention is especially advantageous in that class of web-machines used for the production of books, magazines, and pamphlets and in which it is usual to associate two or more sheets together and fold them simultaneously. This association or collection of sheets is accomplished upon carrier A, which for convenience of illustration is shown in Figs. 1 to 7 as arranged for collecting two sheets in manner similar to that described in Patent No. 197,700.

The cam D, which is pivoted at its lower end and operates the tucking-blades 15, is arranged so that it may be swung out of the path of the rock-arms 1G alternately by means of a connecting-rod 40, to which suitable reciprocations are imparted by means of a cam G, fast upon the shaft of carrier B, and the cam Y, which opens the grippers 6, is also arranged so that it may be swung out of the path of rock-arms 11 alternately by a wristpin 4 on the end of the shaftof carrier l3 and a connecting-rod attached to a rock-arm on the end of the shaft to which said cam Y is attached. (See Fig. 1.)

By this arrangement the forward end of an swungoout of action; but upon the next revolution of carrier A, during which these cams resume their operative positions, a second sheet will be superimposed upon the first, the grippers 6 will open to receive its end, and

though clamping it with the first to carrierA will release both at the proper time for the tucking-blade 15 to tuck both sheets into the nip of the jaw 17, whereupon the two sheets will be folded off onto carrier B and be de livered by cylinder 0.

Although an arrangement of the carriers suitable to the collection of two sheets is shown and is sufficient as illustrative of this operation, it is practicable to make the carrier A of such a size as to collect three or more sheet lengths, as may be desired, by means substantiallysuch as are describedin the patent referred to.

The arms 36, projecting from the shaft 12, which also carries the presser-fingers, are not essential, though they afford a convenient means for bridging the opening in the shell of the carrier B, which is a convenient construction to provide for the carriage of the tapes and yet aid access to the fingers for adjusting the same. As shown, they slightly rock with the shaft, but might be stationary, if desired.

lVhat is claimed is- 1. The combination with a rotative carrier provided with a cutting-blade and adjacent thereto with fingers having means for proj ecting them into contact with the end of the web to clamp the same against a bearing in the opposite carrier, of a companion rotative carrier provided with vibrating grippers operating to bear upon and hold said inwardly projecting web end within the periphery of the carrier, substantially as described.

2. The combination with two carriers, of cutting mechanism, one member of which is carried by each carrier, fingers normally carried within the periphery of one of the carriers and projected therefrom to bend the leading end of the sheet or web immediately after the same has been severed by the cutting mechanism Within the periphery of the IIO other carrier and lap the same upon a supporting-surface therein, and grippers sweeping Within the peripheral line of said latter carrier and operating to clamp said sheet or web onto said surface and carry it onward with the carrier, substantially as described.

3. The combination of the carrier A, its

bearer and vibrating grippers coacting with member of which is carried by the carrier A,

and carrier 13 carrying the other member of the cutting mechanism and having fingers normally carried within its periphery, and means for vibrating the same to lay the sheet end onto said bearer within said carrier A, substantially as described.

4. The combination with the carrier A having a cutting member, an inclined bearer and vibrating grippers hung and vibrated so that their extremities swing Within the peripheral line of the carrier, of the carrier B, its outting-blade and vibrating fingers the latter @0- operating with said bearer in the carrier A to clamp the leading'end of the sheet imme diately behind the cutting-blade against the bearer, substantially as described.

5. The combination with the carriers A and B, the grippers 6 and the vibrating presserfingers 7, of the block 14 having recesses 5, substantially as described.

6. The combination with the carriers A and B, the grippers 6 and the presser-fingers 7, of the inclined bearer 9 and its recess 2 and a cutting-blade cooperating with said recess, substantially as described.

7. The combination With the carriers A and B, the fingers 7 and cutting-blade 13, of the grippers 6 and block 9 having the recess 2 for cooperation with said blade, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
